ECO-S2DA271AA Equivalent & Substitute Parts

Part Overview

The ECO-S2DA271AA is a 270 µF, 200 V aluminum electrolytic capacitor manufactured by Panasonic Electronic Components in the TS-HA series. This radial, can-style snap-in capacitor is designed for general-purpose applications requiring stable capacitance and extended operational life at elevated temperatures. The part is currently obsolete, making equivalent substitutes necessary for ongoing system maintenance and new designs requiring compatible specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ECO-S2DA271AA is determined by strict equivalence across the following critical parameters:

• Capacitance value: 270 µF (exact match required)
• Voltage rating: 200 V (exact match required)
• Tolerance: ±20% (exact match required)
• Package configuration: Radial, Can - Snap-In (exact match required)
• Mounting type: Through Hole (exact match required)
• Lead spacing: 0.394" (10.00mm) (exact match required)
• Can diameter: 0.787" (20.00mm) (exact match required)
• Operating temperature range: -40°C ~ 105°C (minimum requirement)
• Lifetime rating: 3000 Hrs @ 105°C (minimum requirement)

The substitute part LGU2D271MELY from Nichicon meets all critical electrical and mechanical parameters. Physical height variation is acceptable provided the snap-in mounting interface and lead spacing remain unchanged.

Parameter Comparison

Engineering Selection Recommendations

The LGU2D271MELY from Nichicon is a direct functional equivalent to the ECO-S2DA271AA. Both parts share identical electrical specifications: 270 µF capacitance, 200 V voltage rating, ±20% tolerance, and 3000-hour lifetime at 105°C. Both are configured as through-hole, snap-in radial capacitors with matching lead spacing and can diameter.

The LGU2D271MELY offers the advantage of active product status, ensuring continued availability and supply chain stability. Additionally, the Nichicon part is ROHS3 compliant, meeting modern environmental and regulatory requirements, whereas the Panasonic ECO-S2DA271AA is non-compliant.

The LGU2D271MELY has a reduced seated height of 1.181" (30.00mm) compared to the original 1.457" (37.00mm). This dimensional difference must be evaluated against available PCB clearance in the target application. The snap-in mounting interface and lead spacing remain identical, ensuring mechanical compatibility with existing through-hole footprints.

Frequently Asked Questions (FAQ)

Q: Can the LGU2D271MELY be used as a direct replacement for the ECO-S2DA271AA?

A: Yes. Both parts are 270 µF, 200 V aluminum electrolytic capacitors with identical lead spacing (10.00mm), can diameter (20.00mm), and snap-in mounting configuration. Electrical performance and thermal ratings are equivalent. The primary consideration is the reduced height of the substitute part; verify adequate clearance in your PCB layout.

Q: What is the significance of the height difference between these parts?

A: The ECO-S2DA271AA has a maximum seated height of 1.457" (37.00mm), while the LGU2D271MELY measures 1.181" (30.00mm). This 7.00mm reduction does not affect electrical function or mounting compatibility. Confirm that your application has sufficient vertical clearance or that the reduced height presents no interference with adjacent components.

Q: Are there compliance differences between these parts?

A: Yes. The LGU2D271MELY is ROHS3 compliant and REACH unaffected, meeting current environmental regulations. The ECO-S2DA271AA is RoHS non-compliant. For applications subject to RoHS or REACH requirements, the Nichicon substitute is the appropriate choice.

Q: What parameters must match exactly for substitution?

A: Capacitance (270 µF), voltage rating (200 V), tolerance (±20%), package type (Radial, Can - Snap-In), lead spacing (10.00mm), and can diameter (20.00mm) must all match exactly. Operating temperature range and lifetime ratings must meet or exceed the original specification.

Q: Is the ESR specification critical for substitution?

A: The ECO-S2DA271AA specifies 614 mOhm ESR at 120 Hz. The LGU2D271MELY does not provide an ESR specification in the available data. Both parts meet the same ripple current requirement at 120 Hz (1.1 A), indicating functional equivalence for general-purpose applications. If ESR is a critical design parameter, obtain detailed specifications from the manufacturer before final selection.
